Abstract :

The physical and photophysical properties are optimized when a fac-tris[1-methyl-5-(4-fluorophenyl)-3-n-propyl-1H-[1,2,4]-triazolyl]iridium(III) complex core is encapsulated by rigid high-triplet-energy dendrons. Bilayer devices with an electron transport layer has given improved external quantum efficiencies and the time-resolved luminescence measurements have shown that quenching of triplets by the electron transport layer used in the bilayer organic light-emitting diodes has limited the performance.
